The History website tells us; “In one of the greatest upsets in presidential election history, Democratic incumbent Harry S. Truman defeats his Republican challenger, Governor Thomas E. Dewey of New York, by just over two million popular votes. In the days preceding the vote, political analysts and polls were so behind Dewey that on election night, long before all the votes were counted, the Chicago Tribune published an early edition with the banner headline ‘DEWEY DEFEATS TRUMAN.’”
